Fix extension, theme, and accelerator related issue to resolve frequent Firefox related questions.

Several Firefox vulnerabilities are due to enhancements, theme or device accelerations. If so, describe how you can get Firefox back to normal by resetting it to its original defaults and storing your key information at the same time.

If you launch Firefox in Safe Mode, all enhancements are temporary deactivated, hard disk accelerations are deactivated, and the standard theme is used. It will help you find out if any of these causes your problems. Left-click the Menus key, click Help, click the Menus key, click , and then choose .

The Firefox Safe Mode dialogue is used to launch Firefox. If the Firefox Safe Mode screen opens, click the Safe Mode Launch icon. Once Firefox has started in safe mode, test for your issue. When your issue continues in safe mode, it is not a result of an extension, theme, or hard disk accelerator.

Plug-ins or changes to Firefox preferences that are not deactivated in Safe Mode may be other possible causes. Failure to encounter your issue in safe mode is most likely due to an extension, issue, or hard disk accelerator. Follow the procedure in this tutorial to find the cause of your issue.

Some GPUs and video drivers setup may cause Firefox to fail or have problems displaying text or items on pages when using accelerated video technology. They can try turning off hard disk speed to see if it resolves the issue. Once the issue is resolved, it is likely that the cause was caused by accelerated speed.

Otherwise, your issue is likely associated with enhancements or topics. When you use a theme other than the standard Firefox theme: Press the Menus key and highlight . Opens the Add-ons Manager page. Click the Add-ons Manager page to open the Control Panel. Click the Activate icon to change Firefox to the standard theme.

If necessary, click Restart Firefox. When you use a theme other than the standard Firefox theme: Press the Menus key and highlight . Opens the Add-ons Manager page. Click the Add-ons Manager page to open the Control panel. Click the Activate icon to change Firefox to the standard theme.

If necessary, click Reboot Firefox. Once you have restarted Firefox, test for your issue. When it doesn't happen anymore, the design you used caused it. In order to see if an incorrect extension is creating your issue, you can deactivate all your existing extensions: Press the Menus key × and select .

Opens the Add-ons Manager page. Choose the Control panel on the Add-ons Manager page. You can click the name of an extension in the drop-down menu to choose it. To deactivate the extension, click Deactivate. Do this for each of the other enhancements in the queue. On the Firefox Startup page, click Reboot Firefox. When Firefox is restarted, all enhancements will be deactivated.

Check for your issue. So if the issue no longer exists when all your enhancements are deactivated, one of your enhancements has caused it. In order to find the extension that caused your issue, proceed as follows: You can reactivate each extension individually to see which of your deactivated extension files caused your issue.

Press the Menus key and highlight . Opens the Add-ons Manager page. Click the Add-ons Manager page to open the Control panel. You can click the name of an extension in the drop-down box to highlight it. To activate the extension, click Activate. On the Firefox Startup page, click Reboot Firefox. Once you have restarted Firefox, test for your issue.

Once the issue recurs, the just activated extension has caused it. Hint: If you have a large number of expansions, it may be faster to activate more than one expansion at a given moment. With the least number of reboots, the best way is to activate half of the expansions in this queue, then reboot Firefox and test for the issue.

Once the issue recurs, you know that the incorrect extension is one of the ones you just activated. But if the issue does not appear, you know that the incorrect extension is one of the deactivated ones. Continue until the incorrect extension is found. Once you find the extension that caused your issue, deactivate or remove the incorrect extension and reactivate the other extension in the Add-ons pane.

When an extension has caused your issue, it may have an available fix that fixes it: Press the Menus key and highlight . Opens the Add-ons Manager page. Click the Add-ons Manager page to open the Control panel. Once the install is completed, click Restart Firefox. When Firefox is restarted, your Firefox enhancements will be upgraded.

After the extension that causes your issue has had an upgrade, re-enable it and retest for your issue. There are some issues when the extension setting overrides the Firefox setting (e.g. toolbar issues). So you might want to review the extension preferences to see if you can find the item that is giving you your problem: click the shortcut key × and select .

Opens the Add-ons Manager page. Choose the Control panel on the Add-ons Manager page. Click the OptionsPreferences icon for the extension that is creating your issue. Browse through the preferences to see if there is an item that can resolve your issue. When you have found a good way, click Saving and restart Firefox.
